For what it is worth,I ordered some stuff last night to build my "miner"
Using an old "agp" AMD board that has 5 PCI slots. Ordered PCI extender =
cables, and PCI to PCIE adapters. Looking at 5 ATI HD 5830's (maybe best =
bang for the buck).
I am building a custom "open air case" similar =

Where are you getting the 5830s and for how much? I am paying $250ish for
each of the 5870s I am ordering.

Those have 1536 stream processors right? I am trying to get close to that w=
ithout the need for an 8-pin PCIe cable.

1120 stream processors. says it need 2x6 pin PCIE connectors.
Power is going to be a problem maybe. I just ordered a 950w power =
supply, and am considering another one.

Just a heads up, and I am by far no means an expert -- but adding more than
2+ cards to on main board would probably be less effective than having two
cards per main board. I believe you only have so much through put and if you
have a 16x and a 8x they both default to 8x..
Even if I'm wrong you would have an easier time cooling cards, processor,
and main if you split them up. Another benefit would be that a unit failure
wouldn't completely take you offline.
I'm kind of talking out of my rear but that's what I remember anyway..
I'm probably going to be getting 2 68xx's so my 5770 will be for sale if
anyone is interested.
Ill see if I can generate some cash off of them and if not I can fallback to
gaming.

Mining doesn't require much throughput. The calculations aren't transferring
a ton of data. You can hash fast on a 1x slot. You have more power
consumption when you lower the amount of cards per motherboard because you
have extra hardware to supply power to. You also generate more heat because
of more hardware.

What kind of main board are you using to give you enough gpu slots?

From: Lynn Dixon

I agree with Randy. Mining takes almost nill bandwidth across a PCIe bus. I
am running 4 cards on one mainboard and 3 of them are running on x1 slots.
My 4 card righ hashses at about 1500 Megahash per second. Your better off
cramming as many GPU's as you can on one mainboard, less overhead on mutiple
rigs, and easier to maintain. I would add one more card to mine, but I have
no physical room in my case.

how about something like this:

Not even $50.

Hey, do we have a bitcoin pool? I'd like to try it out.
